I've tried to connect a Logitech Wireless USB mouse to my FireBee, and this is what I experienced:

1. When I tried to use the "internal" one, I got no response at boot. FireTos reports nothing in that port. When trying with a memorystick, it is recognized though.

2. When I try to connect to one of the USB ports on the back, the mouse is recognized, however I can only move vertically by moving the mouse horizontally. To move horizontally, I have to press the left mouse button, and then it does move correctly but very irregular.

I understand that there were some issues with USB but this was fixed around new year. Or am I wrong?

I've just booted from a card-reader with a CF-card and an SD-card and it worked just fine from both the "internal" one and the ones in the back.

So, why won't FireTos recognize the mouse when it is connected in the "internal" port, and why does the mouse behave so strange? Any ideas anyone?

So we are talking about FireTOSs built in USB drivers, not about Davids MiNT USB right?

Which FireTOS are you using. Last time I tried it im February, was with the latest official TOS from early December and early January. I got no problems with various mouses (Microsoft, Logitech, etc). I even could use MegaSTE mouse and USB mouse at the same time!
